It is understood that many customers in the purchase of Mitsubishi servo motor, the most troublesome point is the selection of Mitsubishi servo motor. Because the general procurement personnel are not professional industrial control technicians, the specifications of the servo motor and the matching degree with the machine equipment are not very well understood. So here are the different points that you need to pay attention to when choosing Mitsubishi servos!
First, the difference in frequency characteristics
The output torque of the Mitsubishi servo motor decreases as the speed increases, and it drops sharply at higher speeds, so the maximum operating speed is generally 300 to 600 RPM.
Second, the low frequency characteristics are different
Mitsubishi servo motors are prone to low frequency vibration at low speeds. The vibration frequency is related to the load condition and the performance of the driver. It is generally considered that the vibration frequency is half of the take-off frequency of the motor no-load.
Third, the overload capacity is different
Mitsubishi servo motors generally do not have overload capability. Mitsubishi servo motors have strong overload capability.
Fourth, different operating performance
The control of the Mitsubishi servo motor is open-loop control. If the starting frequency is too high or the load is too large, it may be lost or blocked. If the speed is too high during the stop, the overshoot may occur. Therefore, in order to ensure the control accuracy, it should be handled well. The problem of rising and falling speed.
Fifth, the speed response performance is different
It takes 200 to 400 milliseconds for the Mitsubishi servo motor to accelerate from standstill to the operating speed (typically several hundred revolutions per minute). The acceleration performance of the Mitsubishi servo system is better.
